I don't think there's any question, based on rumors and on Apple's (perceived) DNA, that it'll have a high-res (OLED?) 10" screen and some kind of on-screen tactile feedback (see recent rumors & patents). I.e., for Jobs to be extremely pleased with it, it must have at least 2-3 major hardware breakthroughs, outside of any software/content breakthroughs. So plan for the above plus CPU/GPU real power from an Apple-designed ARM+graphics chip, plus some whizzy new (unreplaceable, of course) battery technology. I have to imagine it'll also come with a couple of breakthrough apps like an interactive catalog (see the leaked Ikea mockup) and some kind of virtual-paper-like (or better) interactive magazine/newspaper reader. Jobs wouldn't be happy unless it completely leapfrogged people's expectations.
